IIWPROYBD HANDLE FOR "EDGE-KEYS.

The Schedule referred tain these llhe'lzters- Patent and making part ofthe same.

To all whom it may concern Be it known that LBwmmn A. WooDBnRRY, ofBeverly, in the count-y of Essex and State of Massachusetts,haveinventedanIinprovement in the Handles of Edge-Keys, for iinishingthe Soles ofBoots and Shoes, of which the following is afull, clear, and exactdescription, reference being had to the accompanying drawing making partof -this specification, iu which.- v lFigure l is an elevation of anedge-key, provided with a handle constructed in accordance withmyinvention. Figure 2 is a longitudinal vertical section through thecenter of the same. Edge-keys for finishing and polishing the edge ofthe soles of boots and shoes require to beheatedeprevious to being used,in consequence of which the handle becomes heated bythe tang, or portioninserted therein, to such a'degree that the hand of the operator isburned and rendered callous by the constant use of the tool;furthermore, the interior of the handle is soon charred, so that thetang becomes loose, and requires to be steadied in place by means ofwedges, and, after using theA tool for a short' time, a new haudlebecomes necessary.'

To overcome these objections is the' object of my invention, whichconsists in a handle, provided with `a sleeve, the diameter of aportionof the handle being less than that of the interior of the sleeve, so asto leave an air-space between the two, which prevents the heat-of thetool from being communicated to the hand ot' the operator, as heretoforeand My invention also consists in attaching the shank tothe woodenportion of the handle by means of a plate or disk and screws, wherebyless heat is transmitted to the handle than heretofore, and a means isprovided for readily tightening the shank in the event of its 'becomingloosened by the burning or charring of the end of the handle.

To enable others skilled in the art to understand and use my invention,I will proceed to describe theA manner in which I have carried it out.

In thesaid drawing-ll A represents the shank of the tool, whichflsprovided at one end with 'a circular plate or disk, B, which is rmlysecured to the end of the handle O by means of screws a.

, The handle Gis formed of hard wood, and is sur rounded for the greaterportion of its length by a me tallic sleeve, D, which is slightly.bell-shaped latitsmont-h or lower end.

` The lower halt' of the wooden handle is turned down from b to c, asseen in iig. 2, so as to leave an airspace, d, which prevents theheat'which is communif' cated to the lower portion ofthe handle 0, vfrinthe shank A and disk B, when the tool is ready for use, from heiligtransmitted to the sleeveD, and conse-- quently all liability of thehand of Athe person using the tool being burnt or injured, asheretofore,gis cnt-irely avoided.

By attaching the shank A to the handle C n the manner above described, Iam enabled to dispense with the'long tang or portion which hasheretoforebeen inserted within the handle, andconsequently, much less heat iscommunicated thereto than heretofore, while, if the shank becomes'loosein consequence of the extreme end of the handle O'heooniing burntorcharred, it is merely necessary to'tighten the screws P.
